PROBLEM TO BE SOLVED: To provide a fixing structure of a circuit board, which allows positioning of each of a chassis, the circuit board and a cover to be easily carried out by a simple configuration.SOLUTION: The fixing structure of the circuit board is for attaching the circuit board to a chassis, and a circuit board 3 can be mounted and fixed to a chassis 1 including a bottom surface plate 1a and a side face plate 1b vertical to the bottom surface plate 1a, through a support part 11 between the bottom surface plate 1a and the circuit board. First and second projection parts 12 and 13 to be in contact with a first edge part 3c of the circuit board 3, when the first edge part 3c is mounted on the chassis 1 so as to face the side face plate 1b, are cut and raised upright from the side face plate 1b toward the side of the first edge part 3c, a third projection part 14 to be in contact with a second edge part 3d of the circuit board 3 vertical to the first edge part 3c is also cut and raised upright along the second edge part 3d from the side face plate 1b, and positioning and fixation are carried out with a clearance between the circuit board 3 and the side face plate 1b. |
